A sense of doubt has evolved into a hint of optimism about Derrick Rose's comeback from knee surgery.

The Bulls' guard, who last week mentioned the possibility of sitting out the season, appeared to take another step Monday as he participated in 5-on-5 drills during practice.

"He was able to get out there, and it's good," teammate Kirk Hinrich said. "It was something that (we) as a team needed, as far as every individual coming off the (All-Star) break needed to scrimmage a little bit. And I'm sure it was good for (Rose), helpful to ... give him a good gauge of where he's at."

Chicago head coach Tom Thibodeau said Rose did "what everyone else did" and said his participation wasn't surprising, based on the previously stated outlook. The plan all along was to have Rose return to 5-on-5 action after the break.

Rose cited his inability to dunk as the reason he knew he hadn't fully recovered, and Joakim Noah said Rose still wasn't dunking Monday. The Bulls went through three scrimmages of seven to eight minutes, during which Rose ran fullcourt.

Transaction: The 76ers signed guard Jeremy Pargo for the rest of the season.
